She told magistrate Kay Robertson that she feared that the accused may seek to contact that suspect, a friend of Closter, before his interview.

Detective McIntyre said that Mr Cassai's family strongly opposed bail.

She told defence lawyer Bernie Balmer that the accused, an apprentice plumber, did not own a passport and had never travelled overseas.

She did not agree with Mr Balmer's suggestion that her concerns about Closter being an unacceptable risk could be allayed by special conditions, including living with his father, reporting to police and not contacting witnesses.

Closter's father, Steven Closter, said he was prepared to have his son live with him and also lodge a $5000 surety.

Mr Balmer told the court that his client had no prior convictions and noted his young age and good employment history as an apprentice.

Prosecutor James Henderson said he was concerned about the objective seriousness of the offence and the effect that it had had on the deceased's family.

He also said he was concerned that Closter would interfere with witnesses and, or the co-accused if he was granted bail, where they could "put their heads together" to obstruct the course of justice.

In refusing bail, Ms Robertson acknowledged that Closter was a young man with no prior convictions, with the support of both of his parents.

But she noted she was not here to sentence the accused and her concerns about the allegations that he might interfere with witnesses.

Ms Robertson said if there were a change of circumstances following the interview with the suspect, then a fresh application could be made.

Closter, who was wearing the same white T-shirt, blue board shorts and a pair of thongs as in Wednesday evening's out-of-sessions hearing, sat quietly during the hearing.

He nodded to Mr Balmer from the dock when the lawyer said he would see him in the cells after the case adjourned.

Closter was remanded to reappear for committal mention on April 26.

Speaking outside court later, Mr Balmer said that there were "victims all over the place" in an incident that was a tragedy.

Mr Balmer said that his client was scared and that Closter and his family felt for the deceased's family.

Mr Balmer indicated that there would be a fresh application for bail next week.
